Title: The Quantitative Amino Acid Economy of Yeast Reveals Public versus Private Goods and Guides Syntrophic Community Design
Summary: Using S. cerevisiae, here we establish an absolute, quantitative blueprint of the intracellular and extracellular amino acid economy, defining the fluxes of production, secretion and consumption across 24 hours of cell growth. The data includes absolute intra and extracellular amino acid amounts, amino acid biosynthetic flux for all amino acids, changes in amino acids in yeast auxotrophic strains, and data on amino acid consumption in cells.

1 IMSM_104830 Fig1_2hour Saccharomyces cerevisiae | 4932 Metabolites from S.cerevisiae cells grown in different conditions S. cerevisiae cultures were grown in synthetic defined minimal medium over 2-hours. At specific time points, equal numbers of cells (~2x10^7) were rapidly harvested and immediately quenched by plunging them into an extraction buffer of 60% methanol. Metabolites Estimates of relative amino acid biosynthetic flux in synthetic medium NA NA NA NA 3.0 NA

The quenched cells were extracted in 75% ethanol. The mixture was then dried down using a speed vacuum (rotatory evaporator). The dried metabolites were subsequently dissolved in 300 µl of mass spectrometry-grade water, and 10 µl of this sample was injected for targeted LC-MS/MS analysis.

6 IMSM_104887 Fig2_Ex_2h Saccharomyces cerevisiae | 4932 Metabolites from S.cerevisiae cells grown in different conditions S. cerevisiae cultures were grown in a minimal medium. At 2hours, 1 ml of culture was collected and centrifuged for 5 minutes at 7000 rpm at room temperature to pellet the cells.

Metabolites Absolute concentrations of extracellular amino acids (accumulated in the medium) across the indicated times of growth NA NA NA NA 3.0 NA

The cell-free supernatant was mixed with 75% ethanol to extract extracellular amino acids. The mixture was vortexed for 1.0 minute and placed on ice for a few minutes. Samples were then centrifuged at 16000 rpm for 12 minutes at room temperature. 750 µl of the resulting clear supernatant was transferred to new tubes and dried using a speed vacuum. Dried metabolites were stored at -80°C prior to LC-MS/MS analysis.
